Abstract
Lichtleitstreifen, umfassend einen Lichtleitkörper (3), der massiv ausgebildet ist und eine untere Fläche (32), eine erste Seitenfläche (33), eine zweite Seitenfläche (34) und eine obere Fläche (35) aufweist.Light guide strip, comprising a light guide body (3) which is solid and has a lower surface (32), a first side surface (33), a second side surface (34) and an upper surface (35).
Description
Die Erfindung betrifft eine Fahrzeuglampe und einen Lichtleitstreifen dieser Fahrzeuglampe, wobei die Fahrzeuglampe und der Lichtleitstreifen von Leuchtdioden ein gleichmäßiges Licht erzeugen können.The invention relates to a vehicle lamp and a Lichtleitstreifen this vehicle lamp, wherein the vehicle lamp and the Lichtleitstreifen of light emitting diodes can produce a uniform light.
Aus dem
Bei dieser Fahrzeuglampe kann zwar der Raumbedarf des Tageslichts verkleinert und die Freiheit der Ausgestaltung der Fahrzeuglampe somit erhöht werden, allerdings ist jedoch die Lichtleitwirkung des matten U-förmigen Lichtleitkörpers niedrig. Dadurch ist eine hohe Anzahl von Leuchtdioden erforderlich, so dass die Herstellungskosten hoch sind.In this vehicle lamp, although the space requirement of the daylight can be reduced and the freedom of the configuration of the vehicle lamp can thus be increased, however, the light-guiding effect of the matt U-shaped light-guiding body is low. As a result, a large number of LEDs are required, so that the manufacturing cost is high.
Der Erfindung liegt die Aufgabe zugrunde, eine Fahrzeuglampe und einen Lichtleitstreifen dieser Fahrzeuglampe zu schaffen, wobei die Fahrzeuglampe und der Lichtleitstreifen durch eine kleine Anzahl von Leuchtdioden ein gleichmäßiges Licht erzeugen können.The invention has for its object to provide a vehicle lamp and a Lichtleitstreifen this vehicle lamp, wherein the vehicle lamp and the Lichtleitstreifen can produce a uniform light by a small number of light-emitting diodes.
Diese Aufgabe wird durch den erfindungsgemäßen Lichtleitstreifen gelöst, der umfasst:
einen Lichtleitkörper, der massiv ausgebildet ist und eine untere Fläche, eine erste Seitenfläche, eine zweite Seitenfläche und eine obere Fläche aufweist.This object is achieved by the light guide strip according to the invention, which comprises:
a light guide body that is solid and has a bottom surface, a first side surface, a second side surface, and a top surface.
Der Lichtleitkörper ist U-förmig ausgebildet und hat einen massiven trapezförmigen Querschnitt.The light guide is U-shaped and has a massive trapezoidal cross-section.
Der Winkel zwischen der unteren Fläche und der ersten Seitenfläche sowie der Winkel zwischen der unteren Fläche und der zweiten Seitenfläche liegen beide im Bereich von 60 und 89°.The angle between the lower surface and the first side surface and the angle between the lower surface and the second side surface are both in the range of 60 and 89 °.
Die obere Fläche ist bogenförmig ausgebildet.The upper surface is arcuate.
Die untere Fläche besitzt eine Reflexionsschicht und auf der unteren Fläche sind eine Vielzahl von Positionierelementen vorgesehen, die jeweils ein Positionierloch besitzen.The lower surface has a reflection layer, and on the lower surface there are provided a plurality of positioning members each having a positioning hole.
Die Erfindung betrifft weiter eine Fahrzeuglampe, die umfasst:
einen Hauptkörper, der mindestens eine Nut und eine Trennplatte aufweist, wobei die Trennplatte zwei Durchgangslöcher besitzt, die mit den beiden Enden der Nut verbunden sind;
eine Vielzahl von Leuchtdioden, die über den Durchgangslöchern der Trennplatte angeordnet sind; und
einen Lichtleitkörper, der in der Nut angeordnet ist und mit den beiden Enden durch die Durchgangslöcher geführt wird.The invention further relates to a vehicle lamp comprising:
a main body having at least one groove and a partition plate, the partition plate having two through-holes connected to both ends of the groove;
a plurality of light-emitting diodes arranged over the through-holes of the partition plate; and
a light guide body which is arranged in the groove and is guided with the two ends through the through holes.
Die Nut besitzt entsprechend den Positionierelementen des Lichtleitkörpers mehrere Ausnehmungen.The groove has a plurality of recesses corresponding to the positioning of the light guide.
Die Nut besitzt eine Reflexionsschicht.The groove has a reflection layer.
Daher weist die Erfindung folgende Vorteile auf:
- 1. der Lichtleitstreifen hat einen massiven trapezförmigen Querschnitt und kann das Licht sammeln, wodurch die Helligkeit erhöht wird, so dass nur zwei Leuchtdioden an den beiden Enden des Lichtleitkörpers erforderlich sind, wobei das Licht der Leuchtdioden gleichmäßig im Lichtleitkörper verteilt wird, weshalb die Herstellungskosten reduziert werden;
- 2. beim Fahren am Tag kann eine Warnwirkung für die Fußgänger und Fahrer erzeugen werden, so dass die Verkehrssicherheit erhöht wird.
- 1. the Lichtleitstreifen has a massive trapezoidal cross section and can collect the light, whereby the brightness is increased, so that only two light emitting diodes are required at the two ends of the light guide, wherein the light of the light emitting diodes is uniformly distributed in the light guide, which reduces the manufacturing cost become;
- 2. Driving during the day can create a warning effect for pedestrians and drivers, thus increasing traffic safety.
